GULF OF TEHUANTEPEC GALE WARNING: A COLD FRONT IS APPROACHING THE
NW GULF OF AMERICA. IT WILL SWEEP ACROSS THE REGION OVER THE
NEXT COUPLE OF DAYS. HIGH PRESSURE WILL BUILD IN THE WAKE OF THE
FRONT. THE PRESSURE GRADIENT BETWEEN THIS BUILDING HIGH PRESSURE
AND THE EASTERN NORTH PACIFIC MONSOON TROUGH WILL USHER IN THE
NEXT GULF OF TEHUANTEPEC GALE-FORCE GAP WIND EVENT. FRESH TO
STRONG WINDS OVER THE TEHUANTEPEC REGION WILL INCREASE TO GALE
FORCE THIS EVENING. THE AREA OF HIGH PRESSURE WILL START TO SHIFT
EASTWARD AND WEAKEN ON MON NIGHT. THIS WILL RESULT IN A
SLACKENING OF THE PRESSURE GRADIENT THAT WILL LEAD TO WINDS

DEVELOP TONIGHT AND CONTINUE THROUGH TUE NIGHT, PEAKING AROUND
14 FT (4.5 M). CONDITIONS WILL IMPROVE BY THE MIDDLE OF THE
UPCOMING WEEK.

TO MODERATE NORTHWEST TO NORTH WINDS AND SLIGHT TO MODERATE SEAS
OVER THE OFFSHORE WATERS OF BAJA CALIFORNIA, GULF OF CALIFORNIA
AND OFF CABO CORRIENTES. AN OVERNIGHT SCATTEROMETER SATELLITE
DATA PASS INDICATED FRESH NORTHWEST TO NORTH WINDS OFF PUNTA

MAY HAVE DIMINISHED SLIGHTLY. ELSEWHERE, LIGHT TO GENTLE WINDS
